QoS-Aware Hybrid Scheduling for Geographical Zone-Based Resource Allocation in Cellular Vehicle-to-Vehicle Communications

With a focus on cellular vehicle-to-vehicle (C-V2V) communications, we propose a zone-based hybrid scheduling mechanism through appropriate evolved Node B (eNB) scheduling followed by distributed scheduling to largely reduce the eNBs' loading on signaling and computation but maintain the quality of services of C-V2V communications. More importantly, with the creation of an efficient channel selection algorithm through the proposed co-channel interference estimation and a novel threshold design, our solution could achieve virtually the same link rate of all C-V2V communications as the pure eNB centralized scheme but with substantially lower computation costs and with less traffic for radio resource allocation.
